6.5 Customizing Printer You can customize your TM printer by changing memory switches and the command default value and saving the data onto the NV (nonvolatile) memory. Refer to the next section. 6.5.1 Printer Initial Setting Up Printer initial setting up can be made by memory switches and character code page. Refer to page 44 for details of memory switches. 6.5.2 Changing Command Default Values You can customize your TM by changing the command default value and save the data onto the nonvolatile memory. 6.5.3 Using the NV Memory There is free area in NV memory for user can use. You can use this free area as memo, write other character information or multipurpose. The data is saved even if you turn off the power. Refer to the "ESC/POS Command Reference" on how to read and write. 6.6 Printer Status There are three ways to get the printer status, and each method has the following features. Refer to the ESC/POS Application Guide for details. • Automatic status (ASB): When processed as a normal command, the printer automatically transmits a status message whenever the status changes. It is always necessary to check the ASB status. • Real time status: When the printer receives this command, it responds with the specified printer status. Reporting the printer status takes priority over any normal print data. • Status: The printer transmits a specified printer status in the same way that it processes normal print data. 106 ESC/POS Command-Related Information
